Given numbers are 845,507,637
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 845,507,637 is 124215.
Find LCM of 845,507,637 with Prime Factorization
| 13 | 845, 507, 637 |
| 13 | 65, 39, 49 |
| 5, 3, 49 |
Multiply the prime numbers at the bottom and the left side.
13 x 13 x 5 x 3 x 49 = 124215
Therefore, the lowest common multiple of 845,507,637 is 124215.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
845 x 507 x 637 = 272900355
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
845 : 1, 5, 13, 65, 169, 845
507 : 1, 3, 13, 39, 169, 507
637 : 1, 7, 13, 49, 91, 637
13 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,507,637, is 13.
Now, the common factors can be found like this.
845:5x 13x 13
507:3x 13x 13
637:7x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 13 = 169
Therefore, the value for common factors is 169.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 272900355/(13x169)
LCM = 272900355/2197
LCM = 124215
Thus, we can understand that the LCM of 845,507,637 is 124215.
